django之session配置
session应用示例
1 from django.shortcuts import render 2 from django.shortcuts import HttpResponse 3 from django.shortcuts import redirect 4 5 # Create your views here. 6 user = "a" 7 pwd = "a" 8 def login(request): 9 if request.method == "GET": 10 return render(request,"login.html") 11 elif request.method == "POST": 12 u = request.POST.get("user") 13 p = request.POST.get("password") 14 if u == user and p ==pwd: 15 #session中设置值 16 request.session["username"] = u 17 request.session["is_login"] = True 18 if request.POST.get("rmb",None) == "1": 19 #设置超时时间 20 request.session.set_expiry(10) 21 return redirect("/index") 22 else: 23 return render(request,"login.html") 24 def index(request): 25 #session中获取值 26 if request.session.get("is_login",None): 27 current_user = request.session["username"] 28 return render(request,"index.html",{"current_user":current_user}) 29 else: 30 return redirect("/login") 31 def logout(request): 32 #注销 33 request.session.clear() 34 return redirect("/login")
settings文件内配置
Django默认支持Session,并且默认是将Session数据存储在数据库中,即:django_session 表中。
a. 配置 settings.py
